"Did we just get married?" Hawn jokingly asked Russell as she stepped to the microphone during the ceremony in front of the Eastown apartment complex near Hollywood Boulevard and Gower Street.

"We've never had a celebration like this before. But I'm not going to pop the question," she said. "... I didn't think I was going to be emotional today ... but this actually means more to me as I start reflecting on things."

Russell added, "Today I'm reminded of how lucky I am to have worked and played with so many talented people in a really fun and exciting business -- actors, actresses, directors, producers, writers, all the crew members of all the shows, especially and specially makeup, hair and wardrobe."

Among those joining the couple at the ceremony were Hawn's actress daughter, Kate Hudson; Quentin Tarantino, who directed Russell in "The Hateful Eight," "Grindhouse" and "Death Proof"; and Oscar-winning actress Reese Witherspoon.

The ceremony came one day before the release of Russell's latest movie, "Guardians of the Galaxy Vol. 2," and eight days before the release of Hawn's first film since 2002, "Snatched," playing a mother whose vacation with her daughter (Amy Schumer) goes terribly wrong.

The stars were the 2,609th and 2,610th since the completion of the Walk of Fame in 1961 with the first 1,558 stars. The ceremony was livestreamed on walkoffame.com.
